Landing Gear Structure
Oct 09, 2018

According to the way of bearing and transmitting load, that is, the form of structural force, the landing gear can be divided into three types: truss type, beam type and hybrid type.


The truss type landing gear consists of a truss structure consisting of a space bar and a wheel. The main feature of the framed landing gear is that it connects the wheel to the wing or fuselage through a bearing frame. The rods and the shock absorbing strut in the bearing frame are hinged to each other. They only bear axial forces (in the direction of their respective axes) without being subjected to bending moments. Therefore, the structure of the landing gear has a simple structure and a small mass, and has been widely used in light low-speed aircraft in the past. However, due to the difficulty of retracting, it is usually only used on light aircraft or helicopters that are not very fast.


Beam type landing gear

Beam landing gears usually consist of a force strut, a shock absorber, a torsion arm, a support rod system, a wheel and a brake system. The main bearing members are beams (pillars or shock-absorbing pillars), which can be divided into simple pillars, strut pillars, rocker arms and overhangs depending on the support form of the pillar beams.
